As stated above, the main thing a network connection gives you is IP-VOD (Internet streaming) such as that which comes with Blockbuster@home. You also have the opportunity to buy a Sling Adapter and stream your DVR content in the other direction, e.g. to an iPhone or Android phone, tablet, or PC. And finally your receiver will be able to "phone home", telling Dish of your viewing habits, hardware issues, and other things such as your IP address. (Phone line no longer needed.) If you had multiple receivers on your account, they better all show up from the same address or you could get audited by very small-minded individuals at Dish.
